Forget the extensions. Do it correctly and you will not have any more problems. www.duallyvalve.com. I have used these with PressurePro for over a year and I have not needed to add air yet.
Scott, They will run you abut $65.00 per side (mine did) but they also had the additional valve on each line to allow me to continue using the pressure pros. I don't know if this adds to the cost but I bet this is close regardless. I bought mine from Donely Enterprises. You can find his information on the locate a dealer link under KS(Kansas). I was pointed in his direction because he had the type of crossfires I wanted for the pressure pros but other dealers (maybe even local to you) can get them.

the Milan or the ATVs. Depends on
our compass heading.
The straight braided extensions for inside duals do not have air in them until you apply the air chuck. They have long core extensions in them that push on the valve stem core when an air chuck pushes them.
You can get a rubber plug for the outer aluminum rims that will stabilize them.
We have had them on our 2001 Bounder and now on out 2002 Dutch Star DP with no problems.
Sure makes checking them easy, which I do at every stop.
